This invention relates to chairs in which a folded table plate formstheback of the chair. When unfolded, theimproved chair serves as table.f

At the back of the chair two suitably K curvedflongitudinal barsy arevstationarily fixed tothe back legs of the chair, for instance by screwsand bolts. Said two back rods must be so curved, to enable the easyreception of the folded table -platewhen the improved chair has to serveas seat.

When unfolded-the table plate is supportedat the front of the chair bymeans'of a U# shaped frame; which latter is pivotally fixed to the frontpart-of the chair." `The table plate per seis formed of two platesartcu, Y

lated in any suitable and reliable* manner vat the centre where bothplates join. One Vhalf of the table plate is rigidly connected to the 720 two lfree upper ends of the U- shapedfraine1 whereas the other'halfof the table plateY is laid over said rigidly connected first half ofthe table plate.` In folded position` the U- shaped'frame forms theflash continuation of p the seat and-the folded tablev'plate forms theback ofthe chair. j e

Furthermore a drawer is provided under- Y neaththeseat, which drawer'isso constructed f that it may bedrawn out at the,y right as well'` as atthe lefty ofthe chair frame. Y

One form of execution of the present inven-v tion is shown, by wayof-example, lin the accompanying drawings, wherein-v v Fig. 1 is a topview of theimproved chair,

the table yplatebeing in4 its folded position,y

serving as back of the chair. Y

Fig. 3 is a front elevation-of the chair, according to Fig. 2.

, Fig. 4 illustrates the chair seen from befv hind,` the table platebeing in itsfolded posi-p e tion and servingas back of the chair. Y

. the seat 1 with two front legs 2 andtwo rear stationarilyfxed, fforinstance yby means of 5o bolts and screws. `Said twov longitudinalTheframe of the chair is, as usual, rnadeiof` vare `connectedtogether atlthetop by means of a small transverserod 6,

Said frame f ,v10 Visgpivotallymounted ion vthe front part v of `the chair-.in suchValrnannerthatit may Veasily be raised'` and lowered @When raised,:saidframe butts with `its' front transverse j part against lthefront legsofthe chair, thus giv- 'ginggthe table platefwhen unfolded,a firmsupport'. .,Thetab1e plate per sefConSistSoftWO .to l i plates 11 andy'12 suitably-articulated so as to give av reliableholdfto theentiretable'plate. l

'1 -The plateiall is rigidly connectedinrv any suitable manner, to the.two upper-free extremi-e` ,Y jties ofthe ,ULshaped frame 10.- kThesecond 7 5 plate12,artieulatively connected to the; first plate1'1-is,provided, at itsgbottom surface plate is nnfoldedfandputinposition (Fig.2)

f 1A'knob17 ,i's--so ASituated. at the Ltop @dgeof i the'bottom-'surface 'ofethefplate 12. that` it re5 is left to enable thegripping ofthe knob with A the finger kfor manipulation.' l e p Y eVBetween the legs of the chair afdrawerlV is provided andso constructedthat it maybe pulled out, by` means ofy its knobs 19, 20 either f fromthe right-y or left hand sideofthe chair.

"Suppose, the table plate isr folded together Vand Servesras back lofthechair. y Athe knob 17 with one finger of the right handk j, *l Y"alvldjlft's the folded `table plate 11,'12, which luu One grips thusautomatically raises the U-shaped pivotable frame 10. The back of thechair, e. g. the folded table plate, is raised until the fronttransverse part of the U-shaped frame 10 butts against the front part ofthe chair, that is to say until the frame stands vertical. The plate 12of the table plate is then unfolded, e. g. brought into the stretchedposition (Figs. 2 and 3) until the dove-tailed incisions 15, 16underneath the plate 12 of the table plate engage the extensions 7 and'8of the transverse rod 6. The table plate is thus securely fixed in itsposition.

To bring the table plate into its original position, e. g. as back ofthe chair, it is merely necessary to rip the knob 17 with one finver, tofold the p ate 12 over the plate 11 and to push the thus folded tableplate into the curved ortion of the longitudinal bars 4 and 5 until t elower edge of the @folded table plate `rests on the lowest curvedportion of the longitudinal bars 4 and 5. Once the folded table plate inits position of rest, the U-shaped frame 10 will form the flushcontinuation of 5 the seat l and the chair can serve as seat.

Evidently the several parts of the improved chair may be otherwisedisposed to realize the object of the present invention withoutdeparting from the scope of this in- .so vention as the form ofexecution shown in the drawings is merely by way of example. t

I claim An improved chair comprising a seat, two front legs, two rearlegs in combination with 85 two suitably curved bars fixed to the twohind legs, a small transverse rod the extremities ofv which extendsidewards out of the two curved bars, a. frame pivotally mounted on thefront part of the chair, a table plate consisting of two plates ofwhichthe one plate is rigidly connected to the upperv free ends of thepivotable frame, and the lsecond plate hingedly connected to the firstmentionedk plate so as to enable the folding over of said 5 plate ontothe first plate, two rods on the bottom surface of the second plate, onedovetailed incision in each ofsaid two rodsto engage the extensions ofthe transverse rod when the table plate is in'stretched position. Intestimony whereof I affix my signature.
